The present invention relates-to the roll- Y ing of glass by means of vrolling trains comprising pairs of rolls between which molten glass is pressed and' drawn into plates or 5 sheets. In such glass rolling plants the rolled sheet is usually delivered on a movable receivig tablewhich carries it to, or into, an annealing furnace, the motion of the table being as much as possible synchronized with that of the rolls 1n order to avoid that too quick or too slow a movement of the table might result in unduly stretching or comp acttable and the feeding the sheet betweenthe ing rolls. It is however diicult to obtain perfect synchronism more particularly when the sheet of glass is being printed .while it is rolled, and the Sheets often undergo deformations which result in wasting a notinconthe base of the stationary receiving table and it may be driven by pinions and racks,

or by nuts and screws, being arranged along the sides of the table while the pinions or the nuts are carried by the side plates of the rolling train and are driven from a motor which is mounted on the slidable frame and also drives the rolls for rolling the glass. J

The stationary receiving table may advantageously be located in front of the entrance ofthe annealing furnace, being moved at right angles to said furnace 'and carrying along with it a long and narrow guard or plate which bridges the gap between the tableand the entrance of the furnace, so that the glass sheet may be slid from the table into the furnace without catching in the gap. r

In the accompanying drawings diagrammatically illustrating by way of example various embodiments of my invention:

Fig. 1 is a 'sectional side elevation of a plant with a movable rolling train with rack and'pinion drive,

Fig. 2 being an end elevation and Fig. 3 a plan view of same.

Fig. 4 is a sectional side elevation Showing another form of rolling train.

Fig. 5 is a similar v1ew of a rolling train with nutl and Screw drive. e

In all, the figures of ihe drawing a is the rolling train, b the receiving table and c the entrance of the annealing furnace in `front of which the table b is permanently mounted. The side plates d of the rolling train a on each side ofthe table b rest on the base e of the latter, .which base is provided with Suitable guideways in which the rolling train slides as it delivers the rolled sheet of glass f onto the table.

In Figs. 1 to 4 the trai is produced-by mounted on the inside movement of the rolling means of 4pinions la. of the plates al, said pinions meshing with racks 'i parallel to the sides of the table b and Secured to the base e. Amotor on an outer bracket secured to a plate d drives both the rolls Z, m of the rolling train and the pinion h by means of suitable gears such as shown at fn, in Fig. 2.

The gear ratios are so chosen that the Speed of translation of the rolling train shall correspond with the rate of delivery of the glass so that the glass sheet shall neither be stretched nor compacted when itis deposited on the table by the travelling rolling train;

In Fig. 5 the pinions hand racks i are replaced by rotatable nuts o mounted on the side plates d and threaded rods p secured on both sides of the table b. The nuts o are locked against axial motion by their bearings, and as they are rotated by the motor g they are screwed on the rods p and carry the rolling train forward or backward, as

they turn in one or in the other direction. -As

shown the lnuts 'o 4may be provided on their peripher with helical teeth engaged worm rriven by the motor g.

In' Figsfl and 5 the glass sheet ,f is directly deposited from the rolling train onto the table. In Fig. 4, it is first turned around roll m1 before coming to rest on the table, as described in my co-pending patent application Serial N o. 439,516.

Whatever be the construction adopted, the rolling train a is provided with a narrow plate or guard t trailing after it, which guard tion with fits in the gap between the entrance of the furnace c and the table o, so that as the rolling train moves along, the guard t closes said gap and covers the rack z' or the threaded rod 79 on the base e. rllhe guard t is secured to the side plate d nearest the furnace c and it may be supported by suitable guides. lVlien the glass sheet has reached a position in front of the furnace c, the guard t forms a bridge over which the sheet may be slid from the table b into the furnace.

f course the constructional details herein described and illustrated may be varied without departing from the scope of my invention Vas defined by the appended claims.

I claim:

1. In a glass rolling plant, the combination with a glass annealing furnace, of a stationary table in front of said furnace, said table being separated from said furnace by a gap, a base for said table, a travelling rolling train movable on said base, and means for bridging said gap, said bridging means being carried by said rolling train.

2. In a glass rolling plant, the combination with a glass annealing furnace, of a stationary table in front of said furnace, said table being separated from said furnace by a gap, guideways on each side of said table, a rolling train movable in said guideways, driving means on said rolling train for moving same towards and away from said furnace, and means on said rolling train for bridging said gap.

In a glass rolling plant, the combination with a glass annealing furnace, of a table in front of said furnaceextending at right angles thereto, said table being separated from said furnace yby a gap, guideways on each side of said table, a rolling tra-in movable-1n said guideways, means for moving said rolling train along said guideways, and a guard on said rolling train for closing said gap.

4. In a glass rolling plant, the combinaa glass annealing furnace, of a table in front of said' furnace extending at right angles thereto, a base for said table, said base being of greater width than said table, there being a gap between said table and said furnace, a rolling train movable on said base, means for moving said rolling train along said table, and means on said rolling train for closing said gap.

5.
